The synthetic compounds PFCs that help the fabrics used in rain jackets repel moisture have an unfortunate downside: they don t naturally break down and are far from environmentally-friendly.

PFCs—or perflourinated compounds—are used to treat fabrics so that they repel water, instead of absorbing it.

That molecular bond is so strong, through, that the PFCs typically used on rain jackets and other waterproof gear don t biodegrade over time, and have been found accumulating in nature and even animals.

Over the years outdoor brands have found ways to minimize the amount of PFCs they rely on to waterproof garments, and have developed better versions of them, but the alternative compounds are still far from ideal from an environmental standpoint.

The jacket is only available in white, because Columbia doesn t dye it, which the company said saves over 13 gallons of water per garment during the manufacturing process.

The jacket is also made using 100 percent recycled fabrics, including the plastic from at least 21 discarded water bottles.
